What problems do children often face?

and in what ways can mental arithmetic be beneficial?

Children have trouble concentrating – they are constantly distracted, have difficulty finishing tasks, and struggle to focus on one activity for long.

Mental arithmetic trains concentration, helps children maintain focus, and enables them to navigate tasks more quickly.

Weak memory – children have difficulty remembering new information and quickly forget what they have learned.

Training in mental arithmetic strengthens memory – children remember numbers, formulas, and other school material more easily.

Problems with mathematics and logical thinking – children are afraid of numbers, make frequent mistakes, and take a long time to calculate.

Mental arithmetic teaches children to calculate quickly and accurately, improves logical thinking, and helps them better understand mathematics.
